Astro Note is a 2024 original Japanese TV anime series produced by Telecom Animation Film, airing from April to June 2024.
It follows Takumi Miyasaki, a young chef who moves into the quirky 'Astro House' apartment as a live-in cook.
There, he meets the mysterious and beautiful landlady Mira Gotokuji, who—unknown to most—is actually an alien princess.
With a cast of eccentric tenants, charming comedy, and a touch of sci-fi, Astro Note is a fresh romantic comedy that blends everyday hospitality with intergalactic mysteries.
The series is known for its vibrant animation, heartwarming breakfast scenes, and the delightful chaos of its residents.
Astro Note was born from an idea tossed around over drinks among creators, who wanted to explore “rom-coms” with a nostalgic twist.
Initially envisioned as a mecha-romance hybrid, the project shifted to sci-fi romantic comedy after the mecha angle was scrapped.
Character designer Eisaku Kubonouchi was chosen for his unique art style and “Showa era” feeling, which helped shape the cast’s distinct personalities.
The show slept in development for years before finally getting the green light, earning the description “a miracle project” from its staff.
Astro Note is set in a wooden apartment complex called “Astro House”—a share house with meals included.
The apartment’s charm is its classic, almost retro vibe, reminiscent of Japanese life from past decades, but told through a modern lens.
The residents come from all walks of life, including a struggling idol, a down-on-his-luck novelist, and, hidden among them, Mira—the alien heir to a distant world called Mibo.
The building is a place for characters with personal baggage, each hoping to resolve their issues side-by-side.
Everyday meals at the communal dining table become the heart of the story, bringing everyone together and providing a window into their emotions.
Takumi Miyasaki, a passionate chef, is looking for work and stumbles onto an opening at Astro House—a classic apartment with breakfast included.
He immediately falls for the elegant but clueless landlady, Mira Gotokuji, who can’t cook to save her life and is shockingly unaware of some basics of Earth life.
After winning over the residents with a perfectly fried mackerel, Takumi settles in as the live-in chef.
But strange phenomena start happening around the house—glitches in reality and unexplained occurrences.
As the tenants reveal their quirks, Takumi learns that Mira is actually an alien princess from planet Mibo, hiding her true identity on Earth.
How will this cosmic secret affect Takumi’s growing feelings?
Friendship, romance, and sci-fi mystery mix in a tale that goes from kitchen table to outer space!
Astro House: The central setting, a boarding apartment offering meals, and attracting a quirky mix of residents.
Mibo: A distant planet—Mira’s home world, of which she is the next-in-line royal heir.

Astro Note aired on TOKYO MX and other networks across Japan from April to June 2024, totaling 12 episodes.
A Blu-ray box set containing all episodes will be released on September 25, 2024.
A spinoff short anime series, Sake-Toro Note, was published on social media and offers additional slice-of-life comedy featuring the more boisterous tenants.
Astro Note also featured significant collaboration with the Tokyu Setagaya railway line, including exhibitions and a digital rally event.
The project was helmed by director Shinji Takamatsu and director Haruki Kasugamori, with Kimiko Ueno writing the script.
Animation was handled by Telecom Animation Film, bringing Kubonouchi’s designs to life with a warm, retro-inspired touch.
The writing process saw Takamatsu crafting the series outline while Ueno fleshed out the details, evolving episode-by-episode rather than finishing the whole story up-front.
The team wanted to evoke the feeling of 1980s TV anime while still making the show relevant to today’s viewers—thus, the contemporary setting with a nostalgic backdrop.
Each character was developed with carefully concealed emotional struggles, ensuring the cast was more than just comedic relief.
The series features the bright, upbeat opening “Hohoemi Note” by Ai Furihata, her first anime OP.
The ending, “Kokoro no Kagi” (“The Key to the Heart”), is performed by the lead voice actors Maaya Uchida (Mira) and Soma Saito (Takumi).
Insert songs by Teruko Matsubara’s idol persona and other characters add more musical flavor, highlighting both the comedy and drama.
Astro Note charmed viewers with its lively characters, nostalgic aesthetic, and clever mix of food, romance, and lighthearted sci-fi.
The unique apartment setting, warm comedic style, and emotionally resonant storytelling made it a standout among seasonal anime.
Collaborations with local train lines and cultural exhibitions contributed to its presence beyond the screen, deepening its appeal to both anime fans and urban nostalgic audiences.
A short anime “Sake-Toro Note” featuring Tomihiro Wakabayashi and Teruko Matsubara was released online, giving fans extra comedic moments.
Special events, exhibitions, and digital rallies linked the anime to real locations, creating an immersive experience for fans.
